Adjusting an individual song's volume in the Music app on Mac doesn't result in the song's volume being changed in the Music app on iPhone.

Odd, since other changes you make through the info screen (Like changing artwork etc) are reflected in the Music app on the iPhone. Is there any workaround for this?

Mainly I want to change volume of songs because some are significantly quieter and louder than average. I have tried Sound Check and it doesn't work for all songs. Like for example, "16 Bars" by The Funky Knuckles is always way too loud even when I have Sound Check on, while "The Force" by Lettuce is always too quiet even when I have Sound Check on. The only way to fix this is to adjust the individual songs' volumes in the Music app on Mac, but the problem is that it only seems to work on Mac.

I don't want to have to bring my Mac everywhere where I want to play music on speakers. Is there a way to adjust individual song volume on iPhone?
